In order to achieve the above functions, the present embodiment provides a preferred solution, specifically: the first track groove group 10 is obliquely arranged along the side wall of the driving disc 5; the second track groove group 11 comprises an inclined guide section 14 which is obliquely arranged along the side wall of the driving disc 5 and a straight guide section 15 which is horizontally arranged along the side wall of the driving disc 5; the third track groove group 24 is obliquely arranged along the upper end surface of the rotary bracket 4; the fourth track groove group 12 is obliquely arranged along the upper end surface of the movable bracket 3, and the third track groove group 24 and the fourth driving groove group are staggered. By adopting the preferred scheme, each accessory can be driven by the driving mechanism 7 to perform corresponding motion. I.e. the drive disc 5 is capable of rotational movement relative to the housing; the rotary support 4 can simultaneously perform rotary motion and inward and outward motion relative to the shell in one stage, and can perform rotary motion only relative to the shell in the other stage; the movable bracket 3 can move inwards and outwards relative to the shell in one stage, and can not move relative to the shell under the limit of the limit groove 2 in the other stage; the charging flap assembly 6 moves in one stage in an inward and outward direction and in the other stage in a rotationally separate or split motion.
Preferably, the inclined guiding section 14 is disposed parallel to the first track groove set 10, and the length of the inclined guiding section 14 is equal to the length of the first track groove set 10, so as to ensure the coordination of the actions of the driving disc 5, the rotating support 4 and the moving support 3.

Through the interference that exists between anticreep spacing piece 25 and the driven track groove 23, can prevent that driven transmission pillar 21 from raising warp, break away from driven track groove 23's condition from taking place to ensure the positional relationship of charging cover subunit 13 and movable support 3, guarantee charging cover subunit 13 normal operating.
In this embodiment, an elastic limiting member is disposed between the movable support 3 and the housing 8, an inner end of the elastic limiting member abuts against the movable support 3, and an outer end of the elastic limiting member abuts against the housing 8. By the arrangement of the elastic limiting member and the contact relation between the elastic limiting member and the shell 8, the shaking condition of the movable support 3 can be effectively prevented, and unnecessary interference or collision sound between the cover plate and the shell 8 can be prevented.

Also, since the position of the housing 8 is fixed, the elastic stopper can provide an inward pre-pressing force to the moving bracket 3 to push the moving bracket 3 inward when the moving bracket 3 loses an outward pressing force.
When the invention is used, the working principle is as follows:
1. During the process of switching the splicing state of the initial charging port cover plate assembly 6 to the separation opening state:
the driving mechanism 7 runs the first section to drive the driving disc 5 to rotate and move inwards relative to the shell along the track of the first track groove, the driving disc 5 drives the rotating bracket 4 to synchronously rotate and move inwards relative to the shell along the inclined guide section 14 of the second track groove, and meanwhile, the rotating bracket 4 drives the moving bracket 3 and the charging flap plate assembly 6 to move inwards relative to the shell along the track of the limit groove 2;
the driving mechanism 7 runs at the rear section to drive the driving disc 5 and the rotating support 4 to rotate along the straight guide section 15 of the second track groove relative to the shell, the moving support 3 is static relative to the shell under the limiting action of the limiting groove 2, and meanwhile, the rotating support 4 drives the charging cover plate subunit 13 to switch from the split state to the split opening state through the cooperation of the third transmission member, the third track groove group 24 and the fourth track groove group 12, so that the petal-type opening effect is realized.
The above procedure can be seen with reference to fig. 15, with the broken line indicating the end position of the fittings after the detachment and opening.
